Problems solved by technology

However, the existing thermoelectric generator has a limited efficiency and electric potential when it is formed in a relatively small size.
Since a conventional semiconductor deposition technique is used to manufacture the thermoelectric generator, the thermoelectric generators formed through difficult synthesis processes are subjected to numerous restrictions in process, which lead to disadvantages in size and performance.
These thermoelectric generators cannot provide voltages satisfying input requirements of numerous devices including power control electrons.
However, the wireless sensor node ener...
